Give your headphones the power they deserve

Top-notch headphones are a great way to experience reference-quality sound for a fraction of the price of a high-end loudspeaker system. But if you're plugging your 'phones straight into the headphone jack on your stereo or PC, you could be missing out on the subtle differences that separate great recordings from the merely good ones. That's because a lot of manufacturers use low-cost, low-fi circuitry to drive their headphone jacks  leaving you with uninvolving, one-dimensional sound.

Enjoy a big sonic upgrade

Pro-Ject's Head Box S headphone amp delivers the power you need to bring out the best in your headphones and your tunes. Connect it between your music source and your 'phones to experience richer, deeper bass, clearer highs, and gobs more detail. You'll also hear farther into your favorite recordings for that "you are there" feeling.

Why buy a headphone amp?

High-performance headphones need high-quality amplification to perform up to their full potential. If you connect them directly to the headphone jack on your computer, iPod®, or stereo receiver, you may be disappointed. A separate headphone amplifier sends a stronger, cleaner signal to your headphones.

Features

Overview: The Pro-Ject Head Box S headphone amplifier is a compact
audio amplifier designed particularly to drive headphones. The external headphone
amplifier allows for higher possible volumes and greater audio clarity than the
smaller, inexpensive integrated headphone amplifiers that are used in most of
today's home receivers or audio players. The
Pro-Ject headphone amplifier connects to a line-level (RCA-type) input & output of
your AV
receiver or directly to the line-level (RCA-type) output of your audio source.

Note: Available with a black or silver front-panel.

Construction: The Pro-Ject Head Box S headphone amplifier employs a
metal case to shields the circuitry from vibration and electromagnetic
interference.

Installed for Father In Law

Based on reviews by other people, I felt this was the best way to bring sound to a headset. I wanted a wireless but none had inputs via RCA jacks and plugs. They pretty much went with a miniplug. The TV set I had does not have a miniplug outlet. I left it with my father in law for his TV set. He is hard of hearing. The unit worked was tested by him. We tried it too and it is easier to hear the dialogues which are a bit unclear no matter how loud the TV is turned up - and he has it turned up quite loud. My father in law has been ill and not continued to use it. I got Sony ear buds not headphones, thinking to progress in stages, making an upgrade if he uses it more. Because it will get hot in the summer I don't know if he would want to have headphones could become uncomfortably warm in the summer. I did appreciate the Free 2 -day UPS delivery by Crutchfield by air to Hawaii. It arrived in time, on Christmas Eve.

The unit feels solid and has a simple front panel: On/Off, an LED that lights up when it is on, and a smooth feeling volume control. We could not get it to work off the Samsung LED TV RCA outlets and following someone else's review, hooked it up to the Cable incoming box. The sound on the TV can work at the same time and shutting it off does not affect the sound through the headset. Oddly, the Cable box sound is a tiny bit earlier than the sound coming from the TV set. Overall happy with unit and its performance. Hopefully my Father in Law will find it useful.

Pros:Compact size, simple front panel interface. Connection to RCA inputs on back easily done. Like the weight of the unit as it won't be pulled off the shelf.

Pro-Ject Head Box S

High quality product. Reliable, distortion free sound from the lowest to the highest setting. Metal housing and rubber feet keep product in place. Simple to use. My 86 year old mother was having trouble distinguishing the dialog while watching tv. After I connected this product to her tv cable box and to a pair of headphones she says she can now hear the dialog clearly.

Nice Little Product

I was searching for a means to enjoy better sound quality without spending a great deal of money, and this headphone amplifier has been a great solution. It's compact, sturdy, has an on/off switch (which is very necessary, despite what others may claim), and is simplicity itself to set up and operate. I have it connected directly to a CD player on my desk, and use it with a pair of Sennheiser HD 280 pro headphones. The sound quality is far better than anything one can achieve by plugging headphones into a computer or iPod.

I had a need and Crutchfield had the product

I was in the process of creating a personal sound system for TV viewing, I needed a method of controlling the volume and feed the output to headphones. I told my product advisor all the component parts I was using and he told me about the Pro-Ject Head Box S. My advisor and I connected via Crutchfield's internet system and immedily sent me a link telling me about his recommendation. The rest is history, I received the unit in a couple of days and it works great. I will be expanding the system soon and ordering another.

Fantastic product

Written By JohnH, Massachusetts on Wednesday, July 16, 2014

Sounds great! Rich and detailed. Hearing nuances I haven't heard before. A great product. Plug any device in to it (e.g., IPhone, laptop, CD player) and it dramatically enhances the quality of the audio.

Great Headphone Amp for the money

No need to spend a ton on a headphone amp, in my opinion. This unit works great!I I have it hooked-up through my additional RCA Output jacks on my Mark Levinson 38S Preamp and it sounds fantastic. Crutchfield's service is 2nd to none........highly recommended for speed of shipment and no questions asked returns.

Excellent sounding amp!

This headphones amplifier is absolutely the Best Bang For Your Bucks! I've been using headphones amps for about 15 yrs, and this is the Best performing amp right out lf the box I've ever used.

Pros:Plenty of head room which allows the amp to handle dynamic range in any kind of music or movie. The amp delivers clean smooth sound with no distortion. You can't ask for anything more from an amp in this price range.

Excellent headphone amplifier

I have a set of those Bose super-dupper noise cancelling headphones. I want to listen/watch my "blood-guts-monster" movies that my wife can't stand. This amplifier is fantastic. Simple to use. Great sound reproduction. I plug into my aux out RCA jacks [no head phone jack] on the HDTV and turn down the sound on the HDTV speakers. Nobody can hear my movie but ME ..... Yahoooooo'ey .. my wife can watch the movie [ if she chooses] but can't listen to it LOL LOL LOL .....! Perfect selection to get great sound out of great headphones and watch great "blood-guts-monster" movies.

Works Great

I hooked this this little amp up to the component output of an older portable CD player and was very impressed with the results. It brought the Audio Technica ATH-AD700 headphones I was plugging directly into the CD player into their own. Crisper, highs, clearer bass that was not over emphasized, and a more natural sound stage. It put the quality of my vintage Kenwood Basic home system on my desk. As another reviewer stated, the unit out of the box was good but a little rough; after a couple hours it sounded nothing short of great.

Great little unit

This little unit sounds great. I am not using it conventionally though. I have it hooked up to the variable pre-amp output of a TV. I have the headphone output hooked to a Cambridge Soundworks powered stereo speakers and sub set up. Great clean sound from this mini headphone amp.
